                        TextBox t = tb as TextBox;
                        t.ReadOnly = true;

                }
                foreach (Control ctl in chk_offer.Controls)
                {
                    if (ctl is CheckBox)
                    {
                        CheckBox ck = ctl as CheckBox;
                        if (str.IndexOf(ck.Text) > -1)
                        {
                            ck.Checked = true;
                        }
                    }
                }

if (st == "Public")
                {
                    RadioButton5.Checked = true;
                }
                if (st == "Private")
                {
                    RadioButton6.Checked = true;
                }
                if (st == "Others")
                {
                    RadioButton7.Checked = true;
                }

取值：

 foreach (Control tb in form1.Controls)
            {
                if (tb is TextBox)
                {
                    TextBox t = tb as TextBox;
                    t.ReadOnly = false;
                }
            }

foreach (Control ctl in chk_offer.Controls)
            {
                if (ctl is CheckBox)
                {
                    CheckBox ck = ctl as CheckBox;
                    if (ck.Checked == true)
                    {
                        mp.Product += ck.Text + ",";

                    }
                }
            }

 mp.Product = mp.Product.Substring(0, mp.Product.Length - 1);

   foreach (Control ctl in rad_type.Controls)
            {
                if (ctl is RadioButton)
                {
                    RadioButton rd = ctl as RadioButton;
                    if (rd.Checked == true)
                    {
                        mp.Ownership = rd.Text;
                    }
